November weather forecast
Cozumel, Mexico

The transition towards winter becomes evident in November, with a decrease in daylight and sunshine hours. The sea temperature cools down to 28°C (82.4°F), yet remains warm enough for water activities. Subtle shifts in humidity and UV index indicate the onset of the cooler, drier season. Contrastingly, November experiences a substantial amount of rainfall, with a total of 123mm (4.84") precipitation.

Temperature

Cozumel's November showcases an average high-temperature of a warm 29.7°C (85.5°F), hardly distinct from October's 30.7°C (87.3°F). November's average low-temperature reading settles at an agreeable 21.7°C (71.1°F).

Heat index

The heat index in November is computed to be a very hot 38°C (100.4°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

The average relative humidity in November is 83%.

Rainfall

In Cozumel, in November, it is raining for 11.1 days, with typically 123mm (4.84") of accumulated precipitation. Throughout the year, there are 119.9 rainfall days, and 1490mm (58.66") of precipitation is accumulated.

Note: Between the temperatures of 25°C (77°F) and 29°C (84.2°F), water is considered very warm, providing pleasure in water activities without discomfort over lengthy periods.

Daylight

The average length of the day in November is 11h and 10min.
On the first day of November, sunrise is at 6:49 am and sunset at 6:12 pm. On the last day of the month, sunrise is at 7:06 am and sunset at 6:06 pm EST.

Sunshine

September and November, with an average of 6.1h of sunshine, are months with the least sunshine.

UV index

The average daily maximum UV index in November is 8. A UV Index of 8 to 10 symbolizes a very high health hazard from unprotected exposure to Sun's UV rays for the ordinary person.
Note: A maximum daily UV index of 8 during November morphs into the following directions:
With the absence of protection, damage to skin and eyes can occur instantly. Ensure precautions are taken. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
